Speech Control

Just as with speech, however, we do not have a discrete model in which one viseme has one facial shape, which is held constant until the next viseme. Rather the face is in constant and smooth motion. Furthermore, content plays an important part, just as [Pg.528]

we are not making any claim that TTS was first in any of these developments. [Pg.528]


Another interface technology for effective control and interaction in VEs is speech control. Speech control in virtual environments will fadlitate tasks and exploration. Not tied to tapping onto a keyboard or moving, a control device will free the user s hands and add to the feeling of immersion (lovine 1994). [Pg.2503]

Reverberation Control. Reverberation time (T q) is defined as the length of time in seconds for the sound of an instantaneously stopped source in a room to decay by 60 decibels (dB). Reverberation time is one important factor in determining the acoustical character of a space and its suitabiHty for specific activities. For lectures and other speech activities a relatively short reverberation time is desirable so that syllables do not persist and overlap one another, causing difficulty with inteUigibiHty conversely, for music activities, a relatively long reverberation time is desirable to allow blending of the sound and a sense of being surrounded by the music. Without reverberation music usually sounds dull and lifeless. [Pg.312]

The actual noise levels produced by HVAC systems can var) considerably, and it is not possible to generalize the problems that may be encountered. From a safety point of view, it is advisable to start hearing conservation programs for workers. Permanent hearing damage will result when the noise levels exceed 80 dB(A) for a given time period. Whenever possible, it is desirable to control noise pressure levels to meet the requirements of speech communication in this case noise should not exceed 65-70 dB(A). [Pg.800]

Clinical signs and symptoms of toxicity are related to the overstimulation of muscarinic, nicotinic, and central nervous system receptors in the nervous system. Muscarinic receptors are those activated by the alkaloid drug muscarine. These receptors are under the control of the parasympathetic nervous system, and their hyperactivity results in respiratory and gastrointestinal dysfunction, incontinence, salivation, bradycardia, miosis, and sweating. Nicotinic receptors are those activated by nicotine. Hyperactivity of these receptors results in muscle fasciculations even greater stimulation results in blockade and muscle paralysis (Lefkowitz et al. 1996 Tafliri and Roberts 1987). Hyperactivity of central nervous system receptors results in the frank neurological signs of confusion, ataxia, dizziness, incoordination, and slurred speech, which are manifestations of acute intoxication. Muscarine and nicotine are not... [Pg.102]

H = Headaches. Headaches (particularly those associated with focal neurologic symptoms, such as blurred vision, speech impairment, and/or weakness) may represent strokelike symptoms. Headaches also may indicate poorly controlled blood pressure. [Pg.750]

Slight impairment of balance, speech, vision, reaction time, and hearing. Euphoria. Judgment and self-control are reduced, and caution, reason, and memory are impaired. It is illegal to operate a motor vehicle in some states at this level. [Pg.837]

Morphine is known to produce in human beings a multitude of different side reactions which vary from individual to individual. In a study in which several drugs were compared for their effects on 29 healthy students, using saline control tests, it was found that morphine caused nausea in 18, sleep in 16, drunkenness in 9, dizziness in 13, itching in 9, and indistinct speech in 7.23 The proneness to addiction to morphine is also known to vary from individual to individual and sometimes this drug excites instead of depressing the individual to whom it is administered. [Pg.151]

In SUMMARY, areas of the cerebral cortex can be identified according to the bodily functions which they control. For example, the motor cortex for muscle control, somatosensory cortex for sensory input, visual cortex for visual input, an area concerned with speech, etc. In addition to these specific areas, the cortex also contains highly developed association areas which are probably involved in the complex synthesis of information. [Pg.6]

The first is transport. The air, with its variable components, requires the inspiratory activity of the respiratory muscles—namely, the diaphragm and intercostals (the muscle between the ribs). The action of these muscles is under both voluntary and involuntary central nervous system control thus, gas flow can be adjusted to maintain a steady state of gas exchange. Air must also be provided to the upper airway for speech. [Pg.109]
